Battery life

[Jim@Norcal]

What's a "short life". I use the same type (Marine Deep Cycle) and treat them the same. I'm happy with five years effective life. I use the Flow-Rite watering system (easy) to maintain. I could probably get better life, but I'm not going to disconnect until I buy new ones I use Interstate Marine Deep Cycle from Costco. Blessings

Recently tried to buy the Interstate SRM-4D at Costco. My store didn't have it and wouldn't order it. Ended up getting it from the Interstate distributor.
